Mediastinal abscess cultures were positive for Streptococcus anginosus and Candida albicans. Cultures of the pericardial fluid were positive for Streptococcus anginosus. Pleural fluid had no growth bilaterally.

In primary infections, predominant taxa detected include species of Peptostreptococcus, Parvimonasmicra, Filifactoralocis, and P. alactolyticus, and species of Dialister, F. nucleatum, T. denticola, P. endodontalis, P. gingivalis, T. forsythia, Prevotella baroniae, P. intermedia, Prevotella nigrescens, and Bacteroidaceae [G-1] HOT272 (Siqueira and Rocas 2009). Enterococcus faecalis was detected, but in lower levels. However, in retreatment cases advocated for secondary or persistent endodontic infections, the predominant taxa include Enterococcus species such as E. faecalis, Parvimonas micra, Filifactor alocis, P. alactolyticus, Streptococcus constellatus, Streptococcus anginosus, and Propionibacterium propionicum (Aw 2016; Krishnan et al. 2017).

Polymicrobial and anaerobic isolates are more common in patients older than 15 years of age and in patients with intracranial complications.29,32Streptococcus anginosus species represent some of the most frequently cultured organisms from either orbital or intracranial complications and have a tendency towards abscess formation.33,34 Complications, especially intracranial, are often one-off events due to highly pathogenic organisms. There will be marked local variation in causative organisms and sensitivities, therefore liaison with microbiology colleagues is recommended. An initial regime of intravenous cephalosporin with metronidazole would be an appropriate first choice until case-specific cultures and sensitivities are known. In patients with antibiotic sensitivities, other appropriate antibiotics should be selected in accordance with local microbiology policies.

The patient returned for first follow-up 4 days after hospital discharge, showing a clean healing wound, that was deterged and dressed. The same process was repeated in the next four follow-up visits, and stitches were removed on the 23rd post-op day; however, on the 29th day, the patient returned referring a median epigastric bulg and an episode of fever to 38 °C, still with normal feeding and transit. The visiting plastic surgeon noticed a ballottement in the xipho-umbilical region that was accompanied by erythema of the overlying skin, and pain during the palpation of the abdominal wall. Sixty cubic centimeter of pus were percutaneously drained and the cavity was cleaned using saline solution, hydrogen peroxide and betadine until clear fluid was drained back from it. It was concluded that patient developed a subcutaneous abscess in the epigastric region, and 20°cc of the collected purulent material, as well as a cotton swab, were send for microbiological testing that later determined the positivity to Streptococcus anginosus. The patient pre-emptively began an antibiotic therapy based on Levoxacin 500 mg administration, one pill twice a day.
Epidemiological, Clinical, Microbiological, and Risk Factors of Pyogenic Liver Abscess: An 18-years Retrospective Single-Center Analysis

The abscess culture was only obtained in 96/115 cases (85%), as 15% of the cases showed septicemia prior to the biopsy, improved on antibiotics, and were discharged. Out of the cases biopsied, 37 cases did not show bacterial growth in the abscess culture (39%) which is related to empiric intake of antibiotics. Polymicrobial growth was the most common identified culture results (n = 27, 28%), Escherichia coli was the second most common (n = 15 cases, 16%), Klebsiella pneumonia was the third identified organism (n = 7 cases, 7%). Enterococcus species and Streptococcus anginosus were identified alone in 10% of the patients (Figure 2). Blood culture was obtained in 94 cases, and only 29 cases were positive (30%).
Odontogenic Lemierre’s syndrome with septic superior ophthalmic vein and cavernous sinus thrombophlebitis complicated by blindness and ophthalmoplegia
Published in Orbit, 2023
Donald Tran, Shivesh Varma, Thomas G. Hardy
Lemierre’s syndrome was suspected. After consultation with infectious diseases, empiric intravenous (IV) piperacillin/tazobactam, metronidazole, and vancomycin were commenced. Oral and maxillofacial surgery drained purulent collections from the right pterygomandibular and submasseteric spaces, and the patient was returned to the intensive care unit (ICU) post-operatively. Haematology was consulted, and therapeutic anticoagulation with enoxaparin was commenced. Surgical and blood culture specimens found heavy growth of the Streptococcus anginosus group and multiple anaerobes. Fusobacterium species were not cultured. Following sensitivity results, antibiotics were rationalised to IV ceftriaxone and metronidazole.
